Can provide location technology by user plane and control plane.The secure user plane location (SUPL) that is known as the example of location technology provides location-based service by user plane.
The SUPL technology is the effective ways for the position calculation of transmission mobile radio station (namely location) desired position information.SUPL adopts the user plane data carrier, so that the transmission positioning auxiliary information is auxiliary such as global positioning system (GPS), and carries the agreement that is associated with location technology between portable terminal and network.
Usually, the SUPL network that is associated with location-based service in the location information system comprises SUPL agency, SUPL location platform (SLP) and the terminal (SUPLEnabled Terminal, SEL) of enabling SUPL.The SUPL agency refers to the logical services access point of the positional information of using actual measurement.SLP refers to access network resource therein with the SUPL Service Access Point on the network portion that obtains positional information.SET refers to for the equipment that uses SUPL interface and SUPL network service, for example, the mobile radio station (MS) of the subscriber equipment of UMTS (UE), GSM, IS-95MS, the laptop computer with SET function or personal digital assistant (PDA) etc.SET can also be by one of multiple portable terminal of broadband LAN (WLAN) connection.SET supports various procedures by SUPL definition by be connected to network via user plane bearer.
In the mobile communication system such as location information system, a lot of terminal use's expectations are used different privacy policies according to their current location of terminal.That is to say, the user may expect to receive the Location Request notice based on the current location of his terminal, so that the access of restriction third party location information.For example, can permit the location of his terminal when the user is in, but notify when the user may require to carry out Location Request during in office work.
Thus, can according to the user of request location and in such as the location information system of SUPL network the position (such as family, office etc.) of SET, differently use privacy rule.Therefore, if SET is arranged in the specific region, then the user (third party) who the position message of SET is given the request location before, location server is carried out suitable privacy checking process according to the position of relative users and SET.Preferably, SET, its as can with the equipment of SUPL network service, can be a kind of in the mobile radio station (MS), IS-95MS etc. of subscriber equipment (UE), the GSM of UMTS.In the present invention, SET will simply be called terminal.
Yet the notice of location server is just asked by transmitting notice key element (notification element) to SET simply, and no matter the position of user or SET.Thus, the SET side can't learn corresponding notice request whether position-based (or based on user) carry out, and owing to not knowing that from the time point of the push-notification-answer of SET this causes unsettled system.In the SUPL network configuration, only proposed so far the function of each SUPL equipment, and the signal transmission system that is used for transmission of location information between each SUPL equipment also still under discussion.Therefore, more demands for signal transmission system have been brought.

Embodiment
The present invention can be implemented the network for SUPL.Yet the present invention can be applied to radio (wireless) communication system according to other standard operations.Hereinafter, will be in detail with reference to the preferred embodiments of the present invention.
In the present invention, when application program (namely server system) will send to terminal (or subscriber equipment (UE)) by the Location Request that third party (namely client computer (client) system) makes, application program sends it together with notification mode parameter (designator), this allows terminal to check the notification mode parameter that receives, in order to determine thus what whether notice was carried out based on the position of terminal.If check to such an extent that carry out the put up a notice position that is based on terminal, then terminal keeps the session with terminal, until after the location from location server transmission actual notice key element.The position of terminal carries out if notice is not based on, and then terminal sends conversation end message to the position server.
For this reason, in the present invention, when location-based service (LCS) client requests during as the location of the terminal of enabling SUPL (SET) of target, the SUPL location platform (SLP) in the location server sends initial (SUPL INIT) message of the SUPL that comprises the notification mode parameter to SET.Preferably, the parameter that the notification mode Parametric Representation is such, this parameter indication is common notifying/verifying or location-based notifying/verifying from notice and/or the checking that location server sends.
Usually, in the SUPL network, SLP as location server is made of the SUPL centre of location (SPC) and SUPL place-centric (SLC), this SUPL centre of location (SPC) is for the entity that calculates physical location, and SUPL place-centric (SLC) management SLP other functions except calculating location information, such as roaming, resource management etc.Therefore, in the situation that proxy mode, SET is by communicating by letter with calculating location information via SLC with SPC; And in the situation that non-proxy pattern, SET comes calculating location information by the direct connection of carrying out SPC.
Hereinafter, will explain according to the location-based Notification Method in the location information system of the present invention according to proxy mode and non-proxy pattern.
Fig. 1 illustrates the first embodiment according to the location-based Notification Method in the location information system of the present invention, and it shows the situation that terminal is not roamed under proxy mode.Here, SLP is corresponding to network side, and SET is corresponding to end side.
As shown in Figure 1, when the SUPL proxy requests of LCS client computer from network located SET, the SUPL agency will ask (SLIR) transmission of messages to SLP (S10) by Mobile Location Protocol (MLP) normal place by the Location Request that the LCS client computer is made immediately.MLP SLIR message can comprise ms-id, lcs-client-id, QoP (position quality) etc.
SLP checks based on the lcs-client-id that receives whether certified (mandate) is used for location-based service to the SUPL agency.Then, SLP carries out the privacy checking process based on ms-id and lcs-client-id, namely, checks that from outside privacy entity (PCE) checks based on ms-id and lcs-client-id whether the LCS client computer is allowed the location.SLP can be by asking or directly receive privacy information from PCE to carry out the privacy inspection to PCE.In addition, SLP checks the QoP whether position of the previous SET that calculates meets the demands.
According to the result who checks, if the position of the previous SET that calculates satisfy desired QoP and not needs carry out any notice and/or checking, thereby then the SLP positional value that is directly to the SET that step S19 will before calculate is transferred to the SUPL agency.
On the contrary, if desired QoP is not satisfied in previous SET position of calculating and needs are carried out notice and/or checking, then SLP uses the SET question blank to determine whether SET supports SUPL, and checks with routing iinformation that (affirmations) SET is current and whether belong to service area (namely whether SET is roaming) (S11).
After the privacy inspection of the inspection of finishing SUPL proxy authentication (mandate) and LCS client computer, SLP send conversation initial (namely SUPL INIT) message to SET to initiate thus the location sessions (S12) with SET.SUPL INIT message can be WAP PUSH or SMS trigger, and comprises at least parameter, such as session id (session-id), localization method (posmethod), SLP pattern (namely acting on behalf of/non-proxy), notification mode etc.
The notice that the notification mode parameter is used to allow the identification of SET side to send from SLP is based on the position execution.That is to say, up to the present, SET can not identify the notice that sends from SLP and be the common notice of indication or indicate location-based notice.Therefore, when SLP when notice request, no matter SET inquires and the type of notifying/verifying to SET user, immediately the response results of inquiry sent to SLP afterwards.
Yet when the notice request of being made by location server was based on the notice of position, SET should not send to SLP with push-notification-answer immediately, but should send this push-notification-answer after having carried out the SUPL position fixing process again.
Preferably, common notifying/verifying refers to the notifying/verifying except location-based notifying/verifying, for example based on user's notifying/verifying.
Definition and the type of notification mode parameter have been shown in the table 1.
Table 1
Parameter Exist Value/describe
Notification mode - Whether location-based pattern of notice and checking is described.This parameter can be the type of common notifying/verifying type/location-based notifying/verifying
Reference table 1, the type of notification mode parameter are set to common notifying/verifying or location-based notifying/verifying.Common notifying/verifying is set to " 0 ", and location-based notifying/verifying is set to " 1 ".In addition, when the result according to the privacy inspection required to carry out notice or checking, SLP can be included in the notification mode parameter in the SUPL INIT message.
When receiving SUPL INIT message from SLP, when data connected current not open (setting) to any network, SET was connected to packet data network (for example 3GPP or 3GPP2 network) (S13).Connect to set up in case finished data, then SET be included in notification mode parameter in the SUPLINIT message come examination notice whether position-based carry out.
According to the result who checks, if the notice of being carried out by SLP is not based on the position, then whether SET permits the location according to notification rule to the SET user's query.If the user permits the location, then SET sends SUPL POS INIT message to SLP, if and the user disapproves the location, then the message (not shown) is to SLP for SET transmission conversation end (namely SUPL END), and this conversation end message comprises user's push-notification-answer.Opposite, if notice is based on the position and carries out, then SET will not comprise that the SUPL POS INIT message of any push-notification-answer sends to SLP, this SUPL POS INIT message does not comprise any push-notification-answer (namely keeping push-notification-answer), initiates thus the location sessions (S14) with SLP.
SUPL POS INIT message can comprise session id, SET performance and location identifier (lid) at least.The SET performance can comprise position measurement (location) method (for example the auxiliary A-GPS of MS, based on A-GPS and cell i d (cell-id) method of MS) and position measurement (location) agreement (for example RRLP, RRC and TIA-801) that is associated.In addition, SET can also be provided for the NMR of the radiotechnics (for example GSM:TA and RXLEV) that will use.
When receiving SUPL POS INIT message from SET, the localization method that SLP supports based on SET (posmethod) determines use which kind of location protocol (RRLP, RRC and TIA-801).
Therefore, SLP and SET sequentially exchange the position (S15) that a plurality of position fixing process message (RRLP, RRC and TIA-801) are in succession calculated SET.Based on the measurement result (MS assists) that SLP has received from SET, auxiliary (based on the MS's) that has perhaps obtained from SLP based on SET comes calculating location.
When finishing the SUPL position fixing process, SLP to the PCE request or by using the privacy information that receives from PCE, checks the location that whether allows to have asked the user that locates on the position of the SET that calculates by directly.According to check result, when needs are carried out notice to SET user (namely when permitting conditionally the location of SET), SLP sends and comprises that conversation informing (SUPL NOTIFY) message of notify key element arrives SET (S16).Preferably, the SUPL NOTIFY can comprise session id and notifying parameters.
When receiving the SUPL NOTIFY, SET identifies the notice of being carried out by SLP and is based on the position execution.Then, whether SET inquiry SET user should send the positional value of SET, after this by conversation informing response (namely SUPL NOTIFY RESPONSE) message SET user's push-notification-answer is sent to SLP (S17).Preferably, SUPL NOTIFYRESPONSE message can comprise session id and push-notification-answer parameter.Following definition and the type that the notification type parameter is shown in table 2.
Table 2
Parameter Exist Value/describe
Push-notification-answer - The notifying/verifying response is described whether from user's pattern
The push-notification-answer type M The type of push-notification-answer: allow-do not allow
Thus, after the position of having calculated SET fully, SLP sends SUPL END message to SET, no longer initiates position fixing process (S18) with notice.In addition, when the push-notification-answer of the user in being included in SUPL NOTIFYRESPONSE message is set to " permission ", namely, if SET user permits sending the positioning result value (namely, the current location of the SET that calculates), then SLP will comprise that the MLP normal place of the positional value of SET answers immediately (StandardLocation Immediate Answer, SLIA) message and send to SUPL agency (S19).
As previously mentioned, the present invention can send to SET with the notification mode parameter by SUPL INIT message, so that allowing SET to identify the notifying/verifying that sends from SLP is common notifying/verifying (namely, based on user notifying/verifying) or location-based notifying/verifying.
Fig. 2 illustrates the second embodiment according to the location-based Notification Method in the location information system of the present invention, and it illustrates the situation that terminal is roamed under proxy mode.Here, H-SLP represents the SLP in ownership (home) network, and V-SLP represents the SLP in the accessed network.In addition, request SLP (R-SLP) is illustrated in the initial SLP that connects of external client when initiating the SUPL process in the network.
The second embodiment of the present invention and the first embodiment of the present invention shown in Figure 2 are basic identical, difference is, H-SLP receives Location Request via R-SLP from the SUPL agency, and use the RLP protocol message so that between V-SLP and H-SLP, exchange messages, thereby the beginning of initiating the SUPL session, transmitting location sessions and notice SUPL position fixing process.Especially, when V-SLP utilizes SET to carry out the location, can use the second embodiment of the present invention.
As shown in Figure 2, the SUPL agency is by the location (S20) of MLP SLIR message to R-SLP request LCS client computer.MLP SLIR message can comprise ms-id, lcs-client-id, position quality (QoP) etc.
When receiving MLP SLIR message, R-SLP checks based on lcs-client-id whether the SUPL agency is authorized to for location-based service, and determines H-SLP based on ms-id.In addition, R-SLP checks with routing iinformation that SET is current and whether belongs to coverage (namely, SET whether roaming) (S21).After finishing these a series of operations, R-SLP uses RLP protocol message (namely RLP SLIR) that the request of the location of LCS client computer is sent to H-SLP (S22).
H-SLP carries out the privacy inspection based on ms-id and lcs-client-id, and determines with the SET question blank whether SET supports SUPL.Then, H-SLP determines with roaming information that SET is current and whether is positioned at coverage (namely SET whether roaming) (S23).
If determine that SET supports SUPL and in roaming, then H-SLP send RLP-SSRLIR message to V-SLP to notify: SET will initiate SUPL position fixing process (S24).V-SLP has been ready to be initiated (S25) by RLP-SSRLIA message informing H-SLP:SUPL position fixing process.This RLP-SSRLIR message can comprise at least session id, ms-id and QoP at least, and RLP-SSRLIA message can comprise session id and V-SPC address at least.
Therefore, H-SLP sends SUPL INIT message to the location sessions (S26) of SET with initiation and SET.SUPL INIT message can be WAP PUSH or SMS trigger, and comprises at least session id, localization method (posmethod), SLP pattern (agency/non-proxy), notification mode etc.
When receiving SUPL INIT message from H-SLP, when data connected current not open (setting) to any network, SET was connected to packet data network (for example 3GPP or 3GPP2 network) (S27).Connect foundation in case finish data, then whether SET allows the location according to notification rule to the SET user's query, and comes examination notice whether to carry out based on the position of SET with the notification mode parameter value that is included in the SUPL INIT message.
Be not based on the position of SET if check out the notice of being carried out by SLP, then the SET SUPL POS INIT message that sends the push-notification-answer that comprises SET user is initiated location sessions with H-SLP to H-SLP.Be based on the position of SET if check out the notice carried out by SLP, then SET will not comprise that the SUPL POS INIT message of push-notification-answer sends to H-SLP to begin thus the location sessions (S28) with H-SLP.SUPL POS INIT message can comprise at least session id, SET performance and location identifier (lid) at least.The SET performance can comprise position measurement (location) method (for example the auxiliary A-GPS of MS, based on A-GPS and the cell i d method of MS) and relevant position measurement (location) agreement (for example RRLP, RRC and TIA-801).
When receiving SUPL POS INIT message from SET, H-SLP transmits this SUPL POS INIT message to V-SLP (S29) by RLP-SSRP message.Then, V-SLP determines use which location protocol (RRLP, RRC and TIA-801) based on the localization method (namely posmethod) that SET supports.
Therefore, V-SLP and H-SLP sequentially exchange a plurality of position fixing process message (RRLP, RRC and TIA-801) in succession to calculate the position (S30 and S31) of SET.Auxiliary (based on the MS's) that the measurement that received from SET based on V-SLP (MS is auxiliary) or SET have obtained from V-SLP comes calculating location.
When finishing the SUPL position fixing process, V-SLP sends the SUPL END message (S32) of the positional value of the SET that comprises calculating by RLP-SSRP message.H-SLP is by directly to the PCE request or by using the privacy information that receives from PCE, check the user's who whether allows to ask this location on the position of the SET that calculates location.
According to check result, when needs are carried out notice to SET user (namely when permitting conditionally the location of SET), H-SLP sends and comprises that the SUPL NOTIFY of notifying key element is to SET (S33).When receiving the SUPL NOTIFY from H-SLP, SET identifies the notice that the notice of being carried out by H-SLP is based on the position.Thus, whether SET should send the positional value of SET to the SET user's query, then sends SET user's push-notification-answer to H-SLP (S34) by SUPL NOTIFYRESPONSE message.
Thus, H-SLP sends SUPL END message and no longer initiates position fixing process (S35) to SET to inform.In addition, when the push-notification-answer of the user in being included in SUPL NOTIFY RESPONSE message is set to " permission ", namely, if SET user permits sending positioning result value (the SET current location of namely calculating), then H-SLP will comprise that the MLP SRLIA message of the positional value of SET sends to R-SLP (S36).At last, R-SLP sends the MLP SLIA message of the positional value that comprises SET to SUPL agency (S37).
Fig. 3 illustrates the 3rd embodiment according to the location-based Notification Method in the location information system of the present invention, and it illustrates the situation that terminal is roamed under proxy mode.The third embodiment of the present invention and the second embodiment of the present invention are basic identical, and difference is that H-SLP utilizes SET to carry out the location.
At first, the SUPL agency sends the Location Request (S40) of LCS client computer to R-SLP by MLP SLIR message.R-SLP checks based on lcs-client-id whether the SUPL agency is authorized to for location-based service, and determines H-SLP based on ms-id.MLP SLIR message can comprise ms-id, lcs-client-id and QoP.In addition, R-SLP checks with routing iinformation that SET is current and whether belongs to coverage (namely SET whether roaming) (S41).
After finishing these a series of operations, R-SLP uses RLP protocol message (namely RLPSLIR) to transmit the Location Request (S42) of LCS client computer.H-SLP carries out the privacy inspection based on ms-id and lcs-client-id, and utilizes the SET question blank to determine whether SET supports SUPL.Then, H-SLP determines with routing iinformation that SET is current and whether is positioned at coverage (namely SET whether roaming) (S43).
Support SUPL and roaming if determine SET, then H-SLP send SUPL INIT message to SET to initiate the location sessions (S44) with SET.SUPL INIT message can be WAP PUSH or SMS trigger, and comprises at least session id, localization method (posmethod), SLP pattern (agency/non-proxy), notification mode etc.
When receiving SUPL INIT message from H-SLP, when data connected current not open (setting) to any network, SET was connected to packet data network (for example 3GPP or 3GPP2 network) (S45).Connect foundation in case finish data, then whether SET allows the location according to notification rule to the SET user's query, and comes examination notice whether to carry out based on the position of SET with the notification mode parameter value that is included in the SUPL INIT message.
Be not based on the position of SET if check out the notice of being carried out by SLP, then SET send the push-notification-answer that comprises SET user SUPL POS INIT message to H-SLP, with the location sessions of beginning with H-SLP.Be based on the position of SET if check out the notice carried out by SLP, then SET will not comprise that the SUPL POS INIT message of push-notification-answer sends to H-SLP to begin thus the location sessions (S46) with H-SLP.SUPL POS INIT message can be wrapped and be drawn together at least session id, SET performance and location identifier (lid).The SET performance can comprise position measurement (location) method (for example the auxiliary A-GPS of MS, based on A-GPS and the cell i d method of MS) and position measurement (location) agreement (for example RRLP, RRC and TIA-801) that is associated.
When receiving SUPL POS INIT message from SET, H-SLP transmits the RLP-SRLIR message that comprises ms-id and location identifier (lid) and allows thus V-SLP to calculate rough (coarse) position (S47) of SET.Rough SET position is calculated in V-SLP use location identifier (lid), then transmits the rough position (S48) of the SET that calculates by RLP SRLIA message.
If the rough position of SET satisfies the required QoP of client computer, then H-SLP proceeds to step S53.If do not satisfy, then the localization method (posmethod) supported based on SET of H-SLP determines use which kind of location protocol (RRLP, RRC and TIA-801).
Therefore, H-SLP and SET sequentially exchange the position (S49) that a plurality of position fixing process message (RRLP, RRC and TIA-801) are in succession calculated SET.The measurement result that has received from SET based on H-SLP (MS is auxiliary), or based on auxiliary (based on MS's) that SET has obtained from V-SLP, calculate this position.
When having finished the SUPL position fixing process, H-SLP is by directly to the PCE request or by using the privacy information that receives from PCE, check the location of whether permitting having asked the user that locates on the position of the SET that calculates.According to check result, when needs are carried out SET user's notice (namely, when permitting conditionally the location of SET), H-SLP sends and comprises that the SUPL NOTIFY of notifying key element is to SET (S50).When receiving the SUPL NOTIFY from H-SLP, SET identifies the notice that notice that SLP carries out is based on the position.Then, whether SET should send the SET positional value to the SET user's query, then sends the push-notification-answer of SET to H-SLP (S51) by SUPLNOTIFY RESPONSE message.
Thus, H-SLP sends SUPL END message and no longer initiates position fixing process (S52) to SET to inform.In addition, when the push-notification-answer of the user in being included in SUPL NOTIFY RESPONSE message is set to " permission ", namely, if SET user permits sending positioning result value (current location of the SET that namely calculates), then H-SLP sends the MLP SRLIA message of the positional value that comprises SET to R-SLP (S53).At last, R-SLP sends the MLP SLIA message of the positional value that comprises SET to SUPL agency (S54).
Fig. 4 illustrates the 4th embodiment according to the location-based Notification Method in the location information system of the present invention, and it illustrates the situation that terminal is not roamed under non-proxy pattern.
The fourth embodiment of the present invention illustrates SLP (namely belonging to SLP) is divided into SUPL place-centric (SLC) and the SUPL centre of location (SPC) to carry out position fixing process with regard to its function aspects.That is to say, in the 4th embodiment, SLP is divided into: SPC is used for the position that exchanges messages to calculate SET by the SET with reality; And SLC, be used for to carry out other functions except the function of the positional information of calculating SET of SLP, so that SPC directly utilizes SET to carry out position fixing process, and the information of carrying out between SPC and the SLC via intercommunication transmits.
As shown in Figure 4, the SUPL agency sends the Location Request of LCS client computer to the H-SLC (S60) of SLP by MLP SLIR message.MLP SLIR message can comprise ms-id, lcs-client-id, QoP etc.
H-SLC authorizes SUPL agency based on lcs-client-id, and carries out privacy of user inspection for the LCS client computer based on ms-id.As previously mentioned, can by to the PCE request or by receiving privacy information from PCE, carry out the privacy inspection.
In addition, H-SLC determines with the SET question blank whether SET supports SUPL.If necessary, H-SLC checks with routing iinformation whether in roaming (namely, the current coverage that whether is positioned at of SET) (S61) SET.After finishing these a series of operations, H-SLC can exchange the information required with the SUPL POS session of SET that arranges by internal initialization with H-SPC.
After the inspection of finishing the SUPL proxy authentication and privacy of user checked, H-SLC sent SUPL INIT message and begins SUPL session (S62) with SET to SET.SUPL INIT message can be WAP PUSH or SMS trigger, and comprises at least at least session id, SPC address, localization method (posmethod), SLP pattern (agency/non-proxy), notification mode, mac, secret key id (key-id) etc.
When the H-SLC from SLP received SUPL INIT message, when data connected current not open (setting) to any network, SET was connected to packet data network (for example 3GPP or 3GPP2 network) (S63).SET checks that with the SLP pattern SLP uses proxy mode or non-proxy pattern, in order to send afterwards SUPL authentication request (namely SUPLAUTH REQ) message to H-SLC (S64).SUPL AUTH REQ message can comprise session id, secret key id (key-id) 2 and SET nonce.
H-SLC generates secret key for the mutual authentication (inter-authentication) between SPC and SET with secret key id 2 and SET nonce, and by intercommunication the secret key that generates is sent to H-SPC.Then, H-SPC sends SUPL authentication response (namely SUPLAUTH RESP) message to SET (S65).
When receiving SUPL AUTH RESP message, SET assessment (being similar to) notification rule adopts suitable action.SET comes examination notice whether to carry out based on the position of SET with the notification mode parameter value that is included in the SUPL INIT message.Further, the SET safe IP that is established to V-SPC connects to carry out the mutual authentication with V-SPC.
According to check result, when the notice of being carried out by H-SLP is not based on the position of SET, SET will comprise that the SUPL POS INIT message of SET user's push-notification-answer sends to H-SPC, with the location sessions of beginning with H-SPC.The position of SET carries out if notice is based on, and then SET will not comprise that the SUPL POS INIT message of push-notification-answer sends to H-SPC with the location sessions (S66) of beginning with H-SPC.SUPL POS INIT message can comprise session id, SET performance and location identifier (lid).The SET performance can comprise position measurement (location) method (for example the auxiliary A-GPS of MS, based on A-GPA and the cell i d method of MS) and position measurement (location) agreement (for example RRLP, RRC and TIA-801) that is associated.
Initial position or rough position are calculated in H-SPC use location identifier (lid), and check whether corresponding position satisfies the required QoP of SUPL agency.If the required QoP of SUPL agency is satisfied in corresponding position, then H-SPC is sent to H-SLC via intercommunication with the position of correspondence.H-SLC proceeds to step S73 thus immediately.If the required QoP of SUPL agency is not satisfied in corresponding position, then H-SPC determines use which location protocol (RRLP, RRC and TIA-801) based on SUPL POS INIT message, sequentially exchanging a plurality of position fixing process message (RRLP, RRC and TIA-801) in succession, and carry out thus SUPL position fixing process (S67).
Therefore, H-SPC or SET calculate the position of SET to be used for the location by SUPL position fixing process message.Based on the measurement result (MS assists) that SLP has received from SET, auxiliary (based on the MS's) that has perhaps obtained from SLP based on SET comes calculating location.
When fully having calculated the position of SET, H-SPC inquires what whether notice or checking were carried out based on the position of SET via intercommunication to H-SLC.When notice or checking were based on that the position of SET carries out, H-SPC sent to SET (S68) by SUPL report (namely SUPL REPORT) message with the position of the SET that calculates.
SET sends the SUPL REPORT message that receives and arrives H-SLC (S69), and H-SLC sends and comprises that the SUPL NOTIFY of notifying key element is to SET (S70).The SET that has received the SUPL NOTIFY identifies the notice of being carried out by H-SLC and is based on the position.Whether SET should send the SET positional value to the SET user's query, then by SUPLNOTIFY RESPONSE message SET user's push-notification-answer is sent to H-SLC (S71).
Thus, H-SLC transmission SUPL END message is informed to SET and is no longer initiated position fixing process (S72).When the push-notification-answer of the user in being included in SUPL NOTIFY RESPONSE message is set to " permission ", namely, if SET user permits sending positioning result value (current location of the SET that namely calculates), then H-SLC will comprise that the MLP SLIA message of the positional value of SET sends SUPL agency (S73).
Fig. 5 illustrates the 5th embodiment according to the location-based Notification Method in the location information system of the present invention, and it illustrates the situation that terminal is roamed under non-proxy pattern.The fifth embodiment of the present invention and the fourth embodiment of the present invention shown in Figure 5 are basic identical, difference is: H-SLP receives the Location Request of being made by the SUPL agency via R-SLP, thereby and use the RLP protocol message and initiate the SUPL session in order between H-SLP and V-SLC, exchange messages, transmit location sessions and inform the beginning of SUPL position fixing process.At last, the fifth embodiment of the present invention can be used when V-SPC utilizes SET to carry out the location.
As shown in Figure 5, the SUPL agency is by the location (S80) of MLP SLIR message to R-SLP request LCS client computer.MLP SLIR message can comprise ms-id, lcs-client-id, QoP etc.
The R-SLP that receives MLP SLIR message checks based on lcs-client-id whether the SUPL agency is certified for location-based service, and determines H-SLP based on ms-id.R-SLP also checks with routing iinformation that SET is current and whether belongs to coverage (namely SET whether roaming) (S81).After finishing these a series of operations, R-SLP uses RLP agreement (namely RLP SLIR) message to transmit the Location Request of LCS client computer to H-SLP (S82).
Then H-SLP carries out the privacy inspection based on ms-id and lcs-client-id.H-SLP determines with the SET question blank whether SET supports SUPL, and determines with routing iinformation that SET is current and whether belong to coverage (namely SET whether roaming) (S83).
According to definite result, when SET supports SUPL and is roaming, H-SLP send RLP-SSRLIR message to V-SLC to inform: SET is initiating SUPL position fixing process (S84).In addition, when the result according to the privacy inspection identified that physical location that notice and checking be based on SET user carries out, behind calculating location, H-SLP informed that V-SLC needs to cooperate to use the privacy of user relevant with the LCS client computer between H-SLP and V-SLC.
V-SLC informs V-SPC via internal initialization with the termination of SUPL location sessions.According to the privacy check result, when notice and checking were based on that SET user's physical location carries out, behind calculating location, V-SLC informed that V-SPC needs to cooperate with for LCS client application privacy of user between V-SLC and V-SPC.
In addition, V-SLC informs that by RLP-SSRLIA message the H-SLP:SUPL position fixing process has been ready to be initiated (S85).RLP-SSRLIR message can comprise session id, ms-id and QoP at least, and RLP-SSRLIA message can comprise session id and V-SPC address at least.
Thus, H-SLP sends SUPL INIT message to the location sessions (S86) of SET with beginning and SET.SUPL INIT message can be WAP PUSH or SMS trigger, and comprises at least session id, V-SPC address, localization method (posmethod), SLP pattern (agency/non-proxy), notification mode, mac, secret key id etc.
When receiving SUPL INIT message from H-SLP, when data connect current not open (setting) to any network, SET is connected to packet data network (for example 3GPP or 3GPP2 network) (S87).SET uses SLP pattern examination H-SLP to use agency or non-proxy pattern, in order to send afterwards SUPL AUTH REQ message to H-SLP (S88).SUPL AUTH REQ message can comprise session id, secret key id 2 and SET nonce (SET is current).
H-SLP generates secret key for the mutual authentication between H-SPC and the SET with secret key id 2 and SET nonce, and by intercommunication the secret key that generates is sent to V-SLC (S89).Then, V-SLC is sent to V-SPC by intercommunication with the secret key that generates.H-SLP also sends SUPL AUTH RESP message to SET (S90).
When receiving SUPL AUTH RESP message from H-SLP, SET assessment (being similar to) notification rule is taked suitable action.SET comes examination notice whether to carry out based on the position of SET with the notification mode parameter value that is included in the SUPL INIT message.Further, the safe IP that SET is established to V-SPC connects, with the mutual authentication of execution with V-SPC.
According to check result, when notice is not based on that the position of SET carries out, SET will comprise that the SUPL POS INIT message of SET user's push-notification-answer sends to V-SPC with the beginning location sessions.The position of SET carries out if notice is based on, and then SET will not comprise that the SUPL POS INIT message of push-notification-answer sends to V-SPC with the location sessions (S91) of beginning with V-SPC.SUPL POS INIT message can comprise session id, location identifier (lid) and SET performance at least.
When receiving SUPL POS INIT message from SET, V-SPC informs V-SLC by intercommunication: position fixing process is initiated, and determines use which kind of location protocol (RRLP, RRC and TIA-801) based on the localization method (posmethod) that is included in the SUPL POS INIT message.
Therefore, V-SPC and SET sequentially exchange a plurality of successive position fixes process message (RRLP, RRC and TIA-801) to calculate the position (S92) of SET.The measurement result that has received from SET based on V-SPC (MS is auxiliary), or based on auxiliary (based on MS's) that SET has obtained from V-SPC, come calculating location.
When fully having calculated the SET position, when carry out the position that V-SLC indicates notice or checking to be based on SET via internal initialization after step S84, V-SPC sends to SET (S93) by SUPLREPORT message with the positional value of the SET that calculates, and V-SLC is informed in the end that will locate thus.Thus, V-SLC checks that whether H-SLP has indicated notice or checking to be based on SET in step S84 position is carried out.If indicate, then V-SLC sends RLP-SSRP message and stops (end) (S94) to H-SLP to inform the location.
SET will send to H-SLP (S95) from the SUPL REPORT message that V-SPC receives.Then, H-SLP will comprise that the SUPL NOTIFY of notifying key element sends to SET (S96).The SET that has received the SUPL NOTIFY identifies the notice of being carried out by H-SLP and is based on the position.Then, whether SET should send the positional value of SET to the SET user's query, and then by SUPL NOTIFY RESPONSE message SET user's push-notification-answer is sent to H-SLP (S97).
Thus, H-SLP sends SUPL END message and no longer initiates position fixing process (S98) to SET to inform.When the push-notification-answer of the user in being included in SUPL NOTIFY RESPONSE message is set to " permission ", namely, if SET user permits sending positioning result value (current location of the SET that namely calculates), then H-SLP will comprise that the MLP SRLIA message of the positional value of SET sends to R-SLP (S99).At last, R-SLP will comprise that the MLP SLIA message of the positional value of SET sends to SUPL agency (S100).
